sniffer

Sometimes called a packet sniffer or protocol sniffer. A tool for watching the data flowing in and out of
your computer over the Internet. Sometimes the tool will be specialised just to watch
HTML (Hypertext Markup Language) traffic.

Wireshark, formerly known as
Ethereal, (free). Very easy to use. It watches everything going on via your
Ethernet connection. You can fairly easily trigger a capture to a file. The
problem is overwhelm. By default it captures all traffic on your Ethernet card.
It is not much use for https. Unfortunately, websites are rapidly flipping to
https. It displays gzipped packets without unzipping them first, which is not
much use. To solve problems you have to convince the server to use
http:uncompressed.

OWASP Webscarab gets between your
browser and your server (and reports on the HTTP (Hypertext Transfer Protocol)
conversations going back and forth). It can also deal with
SSL (Secure Sockets Layer). This is a higher level, more convenient,
interface than the Ethereal IP (Internet Protocol)
packet level, but less general.
